# The x87 FP instructions below have debug instr numbers attached -- but the
# operands get rewritten when it's converted to stack-form. Rather than trying
# to recover from this, drop any instruction numbers.
#
## We shouldn't drop numbers from _every_ call though:
# CHECK:  CALLpcrel32 @ext, csr_32, implicit $esp, implicit $ssp, implicit-def $esp, implicit-def $ssp, debug-instr-number 101,
